Does the loading speed of a Rockwell hardness tester affect the hardness value?

The impact of loading speed on hardness values: When the application speed of the main load of the Rockwell hardness tester is changed from 2 seconds to 12 seconds, the impact on the hardness values is 0.2 HRC for low hardness values, 0.4 HRC for medium hardness, and 0.6 HRC for high hardness.
